Selective adsorption of L1210 leukemia cells/human leukocytes on micropatterned surfaces prepared from polystyrene/polypropylene-polyethylene blends

- Surfaces were prepared to adsorb leukemia cells much more than human leukocytes.
- Chemically heterogeneous and micropatterned surfaces were prepared by dip coating.
- Polymer surface roughness was controlled by a phase-separation process.
- PS/PPPE blend surfaces showed considerable selectivity to L1210 leukemia cells.
- L1210 leukemia cells/healthy leukocytes ratio was approached to 9-fold in vitro.
